Description

Technical Field

[0001] The present invention relates to the detection of building materials, and particularly to a device and method for detecting the finished product quality of leveling gypsum. Background Art

[0002] Leveling gypsum is a dry powder material mainly composed of gypsum, supplemented with a variety of additives. After adding water and stirring, leveling gypsum quickly forms a uniform and delicate paste, which can easily fill the unevenness of the wall or floor to achieve rapid leveling. Leveling gypsum has excellent self-leveling performance, can automatically fill fine depressions and gaps, making the surface reach the ideal flatness, providing a perfect foundation for subsequent decoration processes.

[0003] In recent years, with the increasing requirements of people for healthy homes, environmentally friendly homes, and personalized homes, more and more building materials enterprises have begun to focus on the research and development of various environmentally friendly, personalized color, and texture-specific leveling gypsums. In the production and research and development process of leveling gypsum, it is very important to study parameters such as shrinkage, adhesion, crack resistance, anti-hollow drum property, and flatness of leveling gypsum, which are directly related to the final quality of the product. At present, in the process of detecting the performance parameters of gypsum, most still smear the gypsum on the basis of temporarily made concrete blocks. After natural drying or drying in a drying room, the sample situation is directly observed by the naked eye for definition, which is used as the basis for new product research and development and the guiding instructions for construction operations.

[0004] However, this method of temporarily making a smearing base is inconvenient in actual application, and the accuracy is not good, and it also consumes a huge amount of time cost. In particular, it is impossible to simulate the uneven characteristics of the on-site smearing base according to the actual situation. Often, only some concrete blocks with a flat surface are used for replacement, and the defects existing in the actual application of leveling gypsum cannot be truly detected, which has an adverse effect on product research and development. Summary of the Invention

[0030] Figure 4 is Figure 2 the schematic diagram of the structure in the use state of the structure shown in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] As Figure 1A finished product quality inspection device for leveling gypsum shown in the figure is mainly used to assist R & D personnel in conducting simulation experiments during the production of leveling gypsum to detect and verify the parameter indicators of gypsum and provide guiding instructions for subsequent construction. As Figure 1 As shown in the figure, the present invention includes an inspection box composed of a chassis 1 and a machine cover 2. The chassis 1 is generally made of steel components, having good supporting and bearing capacity and structural strength. A detection platform is centrally arranged inside the chassis 1, and the test sample is supported and made through the detection platform.

[0032] The machine cover 2 serves as the top enclosure structure of the present invention. For the convenience of observation, it is generally made of a transparent component and is used to install non-support function components such as a heating irradiation lamp 17, a hot air heating port 18, and a camera 19 for collecting sample images. The hot air heating port 18 is connected to a hot air generator 20 located on the back side of the chassis 1 through a pipeline. The camera 19 is connected to a working platform such as a PC installed with an image processing system and can transmit and save data to the image processing system. The machine cover 2 is usually installed with the chassis 1 in a hinged form. Specifically, the rear side of the machine cover 2 forms an openable and closable hinge with the chassis 1.

[0033] A very important disclosure of the present invention is that the detection platform of the present invention includes a top support plate 3 and a number of vertically telescopic units arranged in a matrix below the top support plate 3. The vertically telescopic unit is a component unit that can form a lift in the vertical direction. The top support plate 3 is a rubber plate. The upper end of the vertically telescopic unit is connected to the top support plate 3, and the surface form of the top support plate 3 can be adjusted by the telescopic height of a number of vertically telescopic units. For example: if a certain vertically telescopic unit descends, the corresponding area of the top support plate 3 will be sunken; if a certain vertically telescopic unit ascends, the corresponding area of the top support plate 3 will rise. It can simulate different conditions of points, lines, and surfaces, reflect various surface conditions of construction bases that may be encountered during the use of leveling gypsum, and achieve precise simulation.

[0034] From the perspective of automation, the vertically telescopic unit of the present invention is preferably a telescopic cylinder, and the upper end of the telescopic cylinder is fixedly connected to the top support plate 3. By controlling the different telescopic amounts of each telescopic cylinder, different forms of the top support plate 3 can be constructed, and convenient and fast automatic control can be realized. However, its overall cost is relatively higher, and it has a more complex electrical design. Therefore, the vertically telescopic unit of the present invention can also be replaced by an adjusting screw 4 with manual adjustment. As Figure 1As shown, that is, the vertical telescopic unit is the adjusting screw 4. To install the adjusting screw 4, a box-shaped supporting buckle plate 5 is also provided in the chassis 1, which is buckled at the bottom of the chassis 1. A number of screw holes matching the adjusting screw 4 are provided on the supporting buckle plate 5, and the adjusting screw 4 is inserted into the screw holes and forms a threaded fit with the supporting buckle plate 5. By rotating the adjusting screw 4, the adjustment of its height can be quickly realized. Of course, in order to facilitate the screwing of the adjusting screw 4, a hexagonal screwing head 6 can be provided at its lower end. This vertical telescopic unit can not only simulate the flatness of the construction foundation in the initial stage, but also simulate the minor deformation of the construction foundation, so as to evaluate its influence on the gypsum layer in turn.

[0035] At the same time, since the adjusting screw 4 needs to rotate during the lifting adjustment process, in order not to interfere with the top support plate 3, the upper end of the adjusting screw 4 and the top support plate 3 are designed to be rotationally matched. Its specific form can be, as Figure 2 shown, an I-shaped section 7 is provided at the upper end of the adjusting screw 4, and an I-shaped cavity matching the I-shaped section 7 is correspondingly provided on the top support plate 3. The I-shaped section 7 of the adjusting screw 4 is inserted into the I-shaped cavity to form a rotational fit with the top support plate 3. This structure of the I-shaped section 7 cooperating with the I-shaped cavity enables the adjusting screw 4 to rotate stably within the top support plate 3 without coming out on the one hand, and on the other hand, the two have better deformation margin at the joint. In the case of a large height difference between adjacent adjusting screws 4, it can better adapt to the trend requirements of the top support plate 3 through its own deformation.

[0036] Since the number of adjusting screws 4 is relatively large, in order to facilitate the adjustment of the adjusting screws 4 in the middle position and prevent the surrounding adjusting screws 4 from blocking the central adjusting screw 4, as Figure 1 shown, the height of the lower end of the adjusting screw 4 of the present invention gradually increases from the center to both sides. An adjustment relief opening 8 is provided on the side wall of the supporting buckle plate 5, and an adjustment door 9 is provided at a position on the side wall of the chassis 1 opposite to the adjustment relief opening 8. By opening the adjustment door 9, the screwing tool can pass through the adjustment relief opening 8 and be correspondingly sleeved on the hexagonal screwing head 6 of the adjusting screw 4 for operation. In order to avoid the influence of slag ash on the rotation of the adjusting screw 4 during long-term use, in fact, a hanging curtain cloth can be provided at the edge of the top support plate 3. Generally, its height and width are such that they can cover the adjustment relief opening to protect the adjusting screw 4.

[0037] In actual working conditions, plaster for leveling is often greatly affected by the moisture penetration of the wall, resulting in mildew, discoloration, and even peeling. Moreover, this moisture penetration is an internal penetration, that is, it comes from inside the foundation (front, ceiling, etc.). To simulate moisture penetration, a moisture penetration hole is vertically provided through the center of the adjusting screw 4 of the present invention. In other words, inside the adjusting screw 4, micropores penetrating both ends are provided, and the micropores are used to introduce moisture to simulate the state of moisture invading the plaster body from the concrete side. The lower end of the adjusting screw 4 is connected to a humidifier through a hose, and the general layout path of the hose enters from the bottom of the chassis 1.

[0038] During use, the present invention adjusts the flatness of the top support plate 3 of the detection platform as needed to simulate the flatness of the construction foundation. A grid cloth is laid on the top support plate 3, and then a layer of 5-10 mm thick concrete mortar is coated on the grid cloth. After the concrete mortar dries, plaster for leveling is scraped on the surface of the concrete mortar. The environmental humidity, environmental temperature, environmental light, and construction foundation deformation degree are simulated in the chassis 1, the simulation data is statistically analyzed, the collected images are transmitted to the image processing system for analysis and processing, and archived.

[0039] Since a large number of samples need to be detected during the detection of plaster for leveling under various simulated working conditions, in order to better clean up the waste materials after use, a better way of the present invention can also be combined with Figure 1 and 3 As shown, slag discharge channels 10 with a right trapezoidal cross-section extending in the front-rear direction are provided in the chassis 1 on the left and right sides of the detection platform, and guide channels 11 inclined from the middle to both sides of the slag discharge channels 10 are provided in the chassis 1 on the front and rear sides of the detection platform.

[0040] After a certain sample is detected, through the repeated up and down movement of each vertical telescopic unit, the concrete layer and the plaster layer for leveling on the top support plate 3 are quickly peeled off and separated, and the waste materials are pushed into the slag discharge channels 10, crushed and conveyed to the slag box 13. On this basis, in order to prevent dust generated by the waste materials, the present invention can also be provided with a spray coil 16 for spraying water into the slag box 13 at the bottom of the chassis 1.

[0041] At the bottom of one end of the slag discharge channel 10 of the present invention, a slag discharge port 12 is provided, and a slag box 13 for collecting slag is provided below the chassis 1. Inside each slag discharge channel 10, three spiral crushing rollers 14 extending in the front-rear direction are arranged side by side, and the three spiral crushing rollers 14 gradually decrease from the inner one to the outer one. This distribution method of the spiral crushing rollers can enable the slag to form extrusion with the spiral crushing rollers under its own gravity, making the pushing effect of the spiral crushing rollers on the slag better. The spiral crushing rollers 14 are connected in transmission, and one of the spiral crushing rollers 14 is connected to a reduction motor 15 arranged outside the chassis 1, and its operation is driven by the reduction motor 15.
